We have a 6 month old kitten that goes mental in the evening, zooming around the place like he's possessed. We have a window ledge outside the 1st floor (about 10ft or so from ground floor) and leave the window open a bit for him to sniff about. Apart from sitting on the ledge, he's never been out on his own. Tonight a neighbour knocked with him in her arms. Apparently she found him in our front garden. I took him upstairs and then noticed his top lip was bloody. Not bleeding, but just looked like he had scraped it. We can only assume that he had been flipping out, as usual, ran onto the ledge and flew right off the other side (window now stays shut!). After a bit of a cuddle I put him down and then noticed he was limping (front right leg). I examined his leg and couldn't feel or see anything wrong. I pressed a bit on his leg/ paw but he didn't flinch or yelp or anything. For about an hour he just lay on the sofa but he has just started to get back to his manic self, all be it a bit subdued and still limping. He does stand on the leg a bit and can run up stairs etc but generally he's holding it up. I've just forked out for having his kn@ckers removed (ironically so he can go out) and I don't really want to fork out even more cash on him if I can help it. Am I right in thinking that it's likely there are no broken bones but probably the equivalent of a twisted ankle or similar? Thanks in advance.
